Sampel Parameter Array

Terkadang berguna untuk membuat, memperbarui, atau menghapus sekumpulan baris dalam database. Ada beberapa pendekatan yang dapat Anda gunakan untuk mencapai tujuan tersebut. Salah satunya adalah meneruskan array informasi dari klien ke prosedur tersimpan integrasi runtime bahasa umum (CLR) di server dengan menggunakan jenis data yang ditentukan pengguna integrasi CLR. Sifat jenis data yang ditentukan pengguna tersebut membatasi ukuran data yang disediakan untuk server hingga 8000 byte. Oleh karena itu, pendekatan ini tidak memuaskan untuk data besar atau kompleks. Jika data yang sedang dimanipulasi kecil dan sederhana, pendekatan ini bisa jauh lebih efisien daripada memanggil prosedur tersimpan untuk setiap baris. Dengan meneruskan array, urutan data dipertahankan untuk aplikasi yang pesanannya signifikan. Sampel ini berisi yang berikut ini:

  1. ContactTypeNames Jenis data yang ditentukan pengguna. Ini berisi daftar nama tipe kontak yang diinginkan.

  2. Prosedur usp_EnsureContactTypeNames tersimpan yang diterapkan sebagai metode Microsoft Visual C# atau Microsoft Visual Basic. Ini menerima instans ContactTypeNames jenis data yang ditentukan pengguna dan menyisipkan baris baru dalam Person.ContactType tabel untuk nama kontak apa pun yang terkandung dalam instans jenis data yang ditentukan pengguna yang belum ada dalam tabel.

  3. Aplikasi TestArrayParameter konsol. Ini membuat instans jenis ContactTypeNames data yang ditentukan pengguna berdasarkan parameter baris perintah yang diteruskan, lalu memanggil prosedur tersimpan dengan meneruskan instans usp_EnsureContactTypeNames jenis data yang ditentukan pengguna sebagai parameter.

Prasyarat

Untuk membuat dan menjalankan proyek ini, perangkat lunak berikut harus diinstal:

  • SQL Server atau SQL Server Express. Anda dapat memperoleh SQL Server Express secara gratis dari SQL Server Express Documentation dan Samples Web site

  • Database AdventureWorks yang tersedia di situs Web Pengembang SQL Server

  • .NET Framework SDK 2.0 atau yang lebih baru atau Microsoft Visual Studio 2005 atau yang lebih baru. Anda dapat memperoleh .NET Framework SDK secara gratis.

  • Selain itu, kondisi berikut harus dipenuhi:

  • Instans SQL Server yang Anda gunakan harus mengaktifkan integrasi CLR.

  • Untuk mengaktifkan integrasi CLR, lakukan langkah-langkah berikut:

    Mengaktifkan Integrasi CLR

    • Jalankan perintah Transact-SQL berikut:

    sp_configure 'clr enabled', 1

    GO

    RECONFIGURE

    GO

    Nota

    Untuk mengaktifkan CLR, Anda harus memiliki ALTER SETTINGS izin tingkat server, yang secara implisit dipegang oleh anggota sysadmin peran server tetap dan serveradmin .

  • Database AdventureWorks harus diinstal pada instans SQL Server yang Anda gunakan.

  • Jika Anda bukan administrator untuk instans SQL Server yang Anda gunakan, Anda harus memiliki administrator yang memberi Anda izin CreateAssembly untuk menyelesaikan penginstalan.

Membangun Sampel

Buat dan jalankan sampel dengan menggunakan instruksi berikut:

  1. Buka perintah Visual Studio atau .NET Framework.

  2. Jika perlu, buat direktori untuk sampel Anda. Untuk contoh ini, kita akan menggunakan C:\MySample.

  3. Di c:\MySample, buat ContactTypeNames.vb (untuk sampel Visual Basic) atau ContactTypeNames.cs (untuk sampel C#) dan salin kode sampel Visual Basic atau C# yang sesuai (di bawah) ke dalam file.

  4. Kompilasi kode sampel ke dalam rakitan yang diperlukan dari prompt baris perintah dengan menjalankan salah satu hal berikut, tergantung pada pilihan bahasa Anda.

    • Vbc /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /target:library ContactTypeNames.vb

    • Csc /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /target:library ContactTypeNames.cs

  5. Di c:\MySample, buat Program.vb (untuk sampel Visual Basic) atau Program.cs (untuk sampel C#) dan salin kode sampel Visual Basic atau C# yang sesuai (di bawah) ke dalam file.

  6. Temukan baris yang sesuai dalam Program file (sekitar baris 24) dan ganti XXX dengan nama instans SQL Server Anda

    • Dim connection As New SqlConnection("data source=XXX;initial catalog=AdventureWorks;Integrated Security=SSPI")

    • using (SqlConnection connection = new SqlConnection("data source=XXX;initial catalog=AdventureWorks;Integrated Security=SSPI"))

  7. Kompilasi kode sampel ke dalam executable yang diperlukan dari prompt baris perintah dengan menjalankan salah satu hal berikut, tergantung pada pilihan bahasa Anda.

    • vbc /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Deployment.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll,C:\MySample\ContactTypeNames.dll /out:TestArrayParameter Program.vb

    • Csc /reference:ContactTypeNames.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /out:TestArrayParameter.exe Program.cs

  8. Salin kode penginstalan Transact-SQL ke dalam file dan simpan seperti Install.sql di direktori sampel.

  9. Jika sampel diinstal di direktori lainnya, C:\MySample\edit file Install.sql seperti yang ditunjukkan untuk menunjuk ke lokasi tersebut.

  10. Menyebarkan assembly, prosedur dan fungsi tersimpan dengan menjalankan

    • sqlcmd -E -I -i install.sql

  11. Uji aplikasi dengan menjalankan baris berikut di prompt perintah:

    • TestArrayParameter "Executive Sales Representative" "Executive Sales Manager"

  12. Salin skrip pembersihan Transact-SQL ke dalam file dan simpan seperti cleanup.sql di direktori sampel.

  13. Jalankan skrip dengan perintah berikut

    • sqlcmd -E -I -i cleanup.sql

Berikut ini adalah daftar kode untuk sampel ini.

Ini adalah kode untuk Pustaka ContactTypeNames.
